Fig, 3 is a HllllihtlVitBW allowing the position elf the two lnenihera when arranged to grip a nut and illnatrating' the manner in whieh a donhle grip one ahorc and the other helow the pivot or l'nl erin'wpoint, in cil'i-actrdl l iex l is a trani-werae Seetio'n laken on the line i 4 ol Fig. 55, and l i 5 illnatratee the two parts that constitute my improved \VlQlliJil eepaiateiill in the prarticai conatrnetion my wrench eoneiati i ol' a main or atationary jaw 1/. integrally l'ormod with its ehank 1/ and lrm'ingthe outer or heel end nhaped to term a han1- mer-hcad fi its shank lacing of uniform ree tang'nlar Shape in cross -aection its entire lei'ro'th with the outer edge nearthelower end l'ormed with serrations or teeth 1/, the reasol'i For which will preeentlj appear.
